Multiblock Turbine

The Multiblock Turbine is a subline feature of Big Reactors. It is a large, complex multi-block structure built from Turbine parts that consumes steam to produce RF and water. The basic parts are:

Arranging these in a valid design will automatically cause a Turbine to assemble; the Turbine will visibly change to have a frame, and any attached controllers will light up.

A Turbine must have at least a 5X5 block base and be 4 blocks high.

Generally if you efficiently design your turbine and efficiently design your reactor, it will increase your RF production of the reactor by itself by around 50%.

This document is up-to-date as of Big Reactors version 0.2.11A.

Building Your First Turbine

To build a very basic Turbine, you will need:

First, place a flat, 5-by-5 square of Turbine Housing down as your Turbine's base. At the moment, Housing is the only thing you can put on the bottom of a Turbine. It should look like this:

Next, build the second layer. Atop the first layer, place 4 pieces of Housing at the corners, like this:

Next, we'll add our first utility blocks. These are blocks that allow you to interact with the Turbine in different ways. We're going to add:

  • A Turbine Controller, which provides a control UI to turn your Turbine on and off, as well as to see its state.
  • A Turbine Power Tap, which allows you to connect any RF-compatible power cable to draw power out of the Turbine.
  • A Turbine Fluid Port, which allows you to insert fuel and remove waste from the Turbine at 360mb/t.

Place these between the Housing blocks on the second layer; they need to be on the outside edges of the Turbine, like so:

To complete the second layer, we'll fill in the Turbine interior and then add Housing. Place a Rotor Shaft in the center of the second layer. Then add 8 iron blocks surrounding it. Then finish the walls for this layer using Turbine Housing. When complete,it should look like this:

To complete the third layer, we'll fill in the Turbine interior and then add Housing again. Place another Rotor Shaft in the center of the third layer. Place 4 Rotor Blades on each side of the Rotor Shaft. Then add the walls for this layer using Turbine Housing. When complete,it should look like this:

Finally the roof should be constructed out of Turbine Housing with a Turbine Rotor Bearing in the center.

When you place the final block into the structure if it is valid it should change to look like this:

Now that it's done, connect your steam up to the Turbine Fluid Port. After it has steam, you can right-click the Turbine Controller and press the Activate button. You should see your Turbine spin up and begin producing power, which will be stored in the Turbine's energy buffer.

A Turbine will buffer up to 1 million RF; any further power produced will be lost. To use this power, place any RF-compatible power conduit, such as Redstone Energy Conduit next to the Turbine Power Tap and connect it to your energy grid.

Construction Rules

A Turbine must be anchored by a sturdy frame. A "frame" is the outline of the Turbine, as if it were a wire-frame drawing. The frame can only be built of Turbine Housing.

A Turbine must be a rectangular prism (a cube or similar shape). Turbine Housing and Turbine Glass can be used to build any of a Turbine's outer surfaces. The side surfaces can contain any of the utility blocks, such as Turbine Controllers, Turbine Rotor Bearing and so on.

A Turbine can only contain 1 Turbine Rotor Bearing.

A Turbine's interior consists of one row or column of Rotor Shafts extending from the Turbine Rotor Bearing to the opposite side. Surrounding the shaft can be either a layer of Rotor Blades extending out from the shaft or a layer of 1 to 8 metal blocks (any vanilla metal blocks or any thermal expansion metal blocks).

All Turbines must have at least one controller.

TIP: Right-click on a disassembled Turbine with an empty hand to see the first reason why the Turbine has not assembled.

Design Principles

When building a larger Turbine, it may help to understand how the design of a Turbine's interior changes how it performs. The positioning of a Turbine's shaft and blades, the number blades, and the contents of any interior space that isn't occupied by Turbine shaft or blades will all change its performance, sometimes dramatically.

Any turbine can take any amount of steam up to 2 buckets per tick but it will be very inefficient if not designed correctly.

In order to design your turbine the only thing you need to worry about is how much steam your Big Reactor is producing. There are two different things that will reduce your Turbines efficiency: For every 25 mb/t of steam that your Big Reactor produces you need to add 1 additional Rotor Blade or it will start to lose efficiency. You also need to get your Turbine's Rotor Speed to be near either 900 RPM or 1800 RPM or else it is less efficient. Also it is more efficient to be at 1800 RPM then 900 by around 6%.

In order to adjust your Rotor Speed higher or lower without changing your steam consumption (aka adjusting your design to your reactor), you need to add or remove metal blocks to your turbine. Each metal block added (by adding a layer to your shaft with 1 to 8 metal blocks surrounding it) increases the amount of steam consumed and RF generated.


Each different metal blocks consumes steam and produces RF at different rates (for 900 RPM):

Iron - Produces 31 RF/t and Consumes 10 Steam mb/t

Gold - Produces 100 RF/t and Consumes 17 Steam mb/t

Invarium - Produces 52 RF/t and Consumes 11 Steam mb/t

Copper - Produces 36 RF/t and Consumes 10 Steam mb/t

Bronze - Produces 50 RF/t and Consumes 11 Steam mb/t

Electrum - Produces 149 RF/t and Consumes 18 Steam mb/t

Fluxed Electrum - Produces 172 RF/t and Consumes 20 Steam mb/t

Enderium - Produces 299 RF/t and Consumes 27 Steam mb/t

(Tested at 900 Rotor Speed)

Enderium produces 606 RF/t and Consumes 55 Steam mb/t at 1800 RPM

Enderium has the highest efficiency and consumes the most steam out of any of the metals for use in your turbine.

Note: These numbers can be influenced by how big your turbine is (bigger with more metal blocks gives a higher efficiency).

For example if your reactor was producing 250 mb/t of steam, to optimally run your turbine at near 1800, you would need 4 blocks of enderium and 1 block of gold (250/55 = 4.54 so 4 blocks of enderium and 30 mb/t left over which is handled by the gold) with 10 turbine blades (250/25 = 10). Which would gives you around 2600 RF/t (606 *4 + 200 * 1 = 2624).

Additionally you can reuse water by having two Turbine Fluid Ports on your turbine. One for importing steam from your Big Reactor and one for exporting water back to your Big Reactor. Turbine fluid ports can only handle 360mb/t of steam, so you may have to include several.
